﻿1. Weidong He*, Kechun Wen, Yinghua Niu. Oriented-attachment Crystals for Energy Conversion Devices, Springer, 2018, ISBN:978-3-319-72432-0. This is the first-ever international book that overviews and analyzes critically recent scientific advances in energy conversion applications of oriented-attachment (OA) materials. Anyone who is interested in gaining insights into the application potentials and research opportunities of OA materials in lithium ion batteries, supercapacitors, fuel cells and solar cells, is highly encouraged to read through the concisely-compiled chapters.

26. Kechun Wen, Kelvin HL Zhang, Weidong He*, et al. Physical justification for ionic conductivity enhancement at strained coherent interfaces. Journal of Power Sources, 2015,285: 37-42. The work addresses a long outstanding issue regarding the quantitative incorporation of lattice strains into the expression of ionic conductivity enhancement, which has puzzled the solid-state physics field for many years.

18. Weidong He*, et al. Out-of-cell oxygen diffusivity evaluation in lithium-air batteries. ChemElectroChem, 2014, 1(12):2052-2057.For the first time, the authors proposed mathematical models and direct methodology to evaluate the oxygen transport phenomena in the Li-air battery. The reviewers speak highly of the work: "The manuscript reports a method of in-situ diffusivity measurement. The rechargeable Li-air battery could be a potentially renewable energy. However, it suffers from cycling fading and low rate capability, mostly resulting from the problem of cathode. Improvements in this problem require new methods to study and oxygen diffisuvity measurements are presented in this study one such method. Authors used electrochemistry for accurate measurement of oxygen diffusivity. The manuscript is generally written and structured well. Therefore, I recommend acceptance as it is." The work is highlighted as Inside Cover in ChemElectroChem.
